采用经典的维量分析法，对滇西北黄背栋林的生物量和净第一性生产力作了初步的研究。发现黄背栎林生物量和净第一性生产力都比较高，生物量３５４．４７６ｔ／ｈｍ￣２、净第一性生产力１７．５６６ｔ／ｈｍ￣２·ａ。认为黄背栎的丛生特性使其森林乔木层密度较大，从而导致较大的生物量和净第一性生产力。但是，黄背栎林为单优势森林，林下更新差，应加强保护以开发林副产品。
Using the classical method of dimensional analysis, we studied the biomass and net primary productivity of Dracaena cirrhosae in northwestern Yunnan. It was found that the biomass and net primary productivity of Quercus mongolica forest were relatively high with a biomass of 354.476 t / hm ~ 2 and a net primary productivity of 17.566 t / hm ~ 2 · a. The clustered nature of Quercus acutissima suggests that the density of forest tree layers is larger, resulting in larger biomass and net primary productivity. However, the yellow-backed oak forest is a single-dominant forest, and the regeneration under the forest is poor. Protection should be strengthened to develop forest by-products.
